What's been shared already is awesome advice. Here's my add.

The easiest way to achieve your goals is through using the Mission Command principles.

These are:

Build cohesive teams through mutual trust.
Create a shared understanding.
Offer clear intent.
Support a disciplined initiative.
Use mission orders.
Accept prudent risk.

Ultimately, 'control' lends towards micromanagement. Although the style is frowned upon in modern leadership, it has its uses. I won't get into those here.

With Mission Command, you're providing guidance so that your team can run with it. You're setting the goal and giving them everything they need to accomplish the mission however they deem fit.

With mutual trust, you know they'll operate within the left and right limits you set.

A shared understanding ensures everyone, down to the lowest level, knows what the company's and their purpose is.

Offering a clear intent means there's no confusion over the goals.

Enabling a disciplined initiative means they'll take charge of situations, acting in everyone's best interest.

Mission orders opens doors for creativity as opposed to task orders. It means you're not spelling out every little detail. Rather, you can explain when you need something to happen in a particular way and if you don't need to, then you can let them have at it.

Accepting prudent risk is vital for growing your business. It requires assessment, mitigation, and action, but enables you to seize opportunities.

Along with these, there are systems that can be emplaced in order to improve efficiency with the process.

This feels like an info dump, but I hope it gave you enough to generate some ideas.

If you sign up with KDP select, you'll be given 5 days where you can drop the price to free. You'll be restricted to only publish on their platform, however.

Hit up your email list, use sites like BookBub, or reddit.com/r/FreeEBooks in order to prepare for the discount launch. Start the deal on a Sunday since more people will be at home and prepared to read rather than Friday and Saturday nights when they're out.

Include, at the end of your book, a request for people to leave honest feedback. They're more apt to do it if you remind them. You can also include links to your other titles.

I've published a handful of titles under different pen names but I'm not an expert. I just figured I'd share what my research picked up.

I don't think leadership and management will ever be mutually exclusive.

It's a battle of semantics. A manager has subordinates, a leader has followers. Since following is a voluntary action, a manager would have to give up authoritative control.

Still, employees can choose whether to follow you, or just acknowledge your orders.

Management skills are what identify that baseline of performance and use it to maximum efficiency. Leadership skills provide motivation so that baseline is increased.

Without a combination of these skills, you're missing out on the full potential of your team.

I would argue that being a "managing leader" is more important than ever to develop a successful team and business.
